I have a strane feeling all Triton motherboards have the feature(?) as the IDE controller is part of the chipset. Or am I again remebering falsely? Perhaps not as Win95 tends to recognise it's there (but say that bus mastering is not supported). So are 486 motherboards based on the SiS chipset and most probably also several others. > > ========================================================================== > Chuck Robey chuckr@eng.umd.edu, I run FreeBSD-current on n3lxx + Journey2 > > Three Accounts for the Super-users in the sky, > Seven for the Operators in their halls of fame, > Nine for Ordinary Users doomed to crie, > One for the Illegal Cracker with his evil game > In the Domains of Internet where the data lie. > One Account to rule them all, One Account to watch them, > One Account to make them all and in the network bind them.
